sergey-safarov created an issue (kamailio/kamailio#4457)

### Description

For now, `htable` exporting `table_spec` and `init_tables`. [Link](https://github.com/kamailio/kamailio/blob/18beef305002e6b2a4a6504273a33db3aa...)

When spec contains `dbmode=1`, then data is not loaded from the database, and `htable` cache data is not available after Kamailio restart.

It would be fine to expose `ht_db_load_tables` via `htable` API and other Kamailio modules can get cache after Kamailio restart.

### Expected behavior htables defined via API with param dbmode=1 loaded after Kamailio restart.

#### Actual observed behavior htables cache is not loaded after Kamailio restart if the table is created via API.

### Possible Solutions

Probably it can be done using this change ```diff From 72e1aea56efa16ecd50806baa94a5cc0f62d37d6 Mon Sep 17 00:00:00 2001 From: Nikolay Ivanuschak ivanuschak.nikolay@gmail.com Date: Wed, 29 Oct 2025 22:57:49 +0300 Subject: [PATCH] htable: added db API functions
